Four Underbets in One Hand

This wasn’t anything that I planned from the get-go. It was just that on each street, I kept feeling like he could be weak enough for an underbet to show a profit. I almost shoved the turn, and then I was like, “Screw it, 80% of what he folds to a shove probably folds for 1/3 pot”. Given that he called, that might not be true, but it just made the river shove that much more profitable. By the way, Villain has only about $260 left in his stack, so even though I potted it, the shove was effectively half-pot.
